Product details

0.50mm Pitch Mezzanine Header — 40 Positions, 3.5mm Stack

The Hirose DF12(3.5)-40DP-0.5V(86) is a 40-position, dual-row header from the DF12 series, built for board-to-board stacking at a fixed 3.5mm mated height. The 0.50mm pitch (0.020") drives a dense footprint — trace escape from inner rows needs micro-vias or tight neck-downs on the PCB. Outer shroud contacts protect the mating interface during blind-mate assembly.

Board Layout Fit — SMT, Board Guide, Solder Retention

The board guide aligns the header during reflow, and the solder retention pads anchor the part against shear from cable or card insertion. Height above board is 2.80mm (0.110"), so the total Z-budget after stacking to the mating receptacle is the 3.5mm stack height — no extra clearance needed above the header body.

Frequently asked questions

Where to buy DF12(3.5)-40DP-0.5V(86) available via RFQ confirmation?

DF12(3.5)-40DP-0.5V(86) is obsolete and sourced to order through independent distribution.

What is the exact stacking height of DF12(3.5)-40DP-0.5V(86)?

The mated stacking height is 3.5mm — fixed by the header and its matching receptacle, no adjustment.

What is the replacement for DF12(3.5)-40DP-0.5V(86)?

Current-production DF12 series headers at the same 0.50mm pitch and 3.5mm stack height are the closest functional match — verify position count and footprint before specifying.
